EtherAppServer

simple module

Server side of the EtherAppClient model -- generates packets containing EtherAppResp chunks with the number of bytes requested by the client in corresponding EtherAppReq. It should be connected directly to Ieee8022Llc module.

Used in compound modules

Name	Type	Description
EthernetHost	compound module	An example host with one Ethernet port and a traffic generator that generates request-reply traffic directly over Ethernet. This host model does not contain higher layer protocols (IP, TCP). By default it is configured to use half-duplex MAC (CSMA/CD).

Parameters

Name	Type	Default value	Description
localSAP	int	0xf1
stopOperationExtraTime	double	-1s	extra time after lifecycle stop operation finished
stopOperationTimeout	double	2s	timeout value for lifecycle stop operation
